Neutral strange particle production in\(\bar v\) Ne charged current interactions is studied using the bubble chamber BEBC, exposed to the CERN SPS antineutrino wide band beam. From a sample of 1191 neutral strange particles, the inclusive production rates are determined to be (15.7±0.8)% forK0 mesons, (8.2±0.5)% for Λ, (0.4±0.2)% for\(\bar \Lambda \) and (0.6±0.3)% for Σ0 hyperons. The inclusive production properties ofK0 mesons and Λ hyperons are investigated. The Λ hyperons are found to be polarized in the production plane.

Antineutrino interactions in BEBC are compared to look for differences between the differential cross sections per nucleon in neon and in deuterium. The identical geometries, beam spectra and muon identification criteria and acceptances allow comparison with very small systematic errors. The results are compared in detail with μ and e scattering data from EMC and SLAC. We find no rise in the ratio d σ/ d x ( ν Ne )/σ/ d x ( ν D 2 ) at low x , independent of Q 2 up to Q 2 ∼ 14 GeV 2 .
